I bought the backup camera maybe 18 months ago. I’m really happy with the view provided on my iPhone BUT…
I originally had an iPhone-7 and it took me weeks to figure out a sequence of closing the app that would shut down the camera’s WiFi. I recently upgraded to an iPhone-XR and I’m ready to throw the camera in the trash. First, I noticed the same issue that I had originally with the iPhone-7. This time, I was determined to resolve it quickly so I removed the camera from the car and experimented from the comfort of my living room. I spent five hours (with no success) trying to resolve the issue.
I found several app shut-down sequences that would leave the WiFi ON permanently. I also found several shut-down sequences that APPEARED to work properly but, two minutes later, the WiFi came back on. Two minutes after that, The WiFi went off again and continued OFF/ON at two minute intervals indefinitely.
If Zus will not update the app to provide a WiFi OFF switch, this camera is totally useless to me.
